Oxidation

Johnson Matthey Chemical Products spectrum includes platinum group metal compounds with a wide variety of ligands: amines, phosphines, carbonyls, alkenes and dienes, halides, aromatics and nitriles. These can be used for the homogeneously catalysed oxidation of alcohols and amines. We can also supply potassium osmate for the dihydroxylation of alkenes to diols, ruthenium homogeneous catalyst precursors for the oxidative cleavage of alkenes and palladium homogeneous catalyst precursors for Wacker oxidation.

BenefitsThis product contains osmium in oxidation state VI, which is highly reactive.

ApplicationPotassium osmate is used as a homogeneous catalyst for the cis-dihydroxylation of olefins. The reaction converts the olefin to a cis-diol via a cyclic osmate ester intermediate. Osmium tetroxide can be used to catalyse this reaction, but potassium osmate is often preferred due to the hazards associated with the volatility and toxicity of osmium tetroxide.
